FreeCAD

FreeCAD is a free and open-source parametric 3D modeling application made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history to change its parameters.

FreeCAD is designed to fit a wide range of uses including product design, mechanical engineering, architecture/BIM, model analysis and much more, and will care for you whether you are a hobbyist, programmer, experienced CAD user, student or teacher.

FreeCAD runs on Windows, macOS and Linux.

This opencollective account is part of multiple efforts by the FreeCAD community of developers and users to allow people and companies to give financial support to FreeCAD and its developers. These efforts are organized by the FreeCAD Project Association.
